Abstract

A switchover valve (20) is employed within a heat pump system (10) including a heat exchanger coil (14) within a structure (18) to be heated and cooled, and a second heat exchanger coil (16) external of the structure and in fluid communication with the first coil. The system also includes a compressor (12) which circulates a refrigerant between the coils to effect a net heat transfer into or out of the structure. The switchover valve operates to selectively reverse the flow of refrigerant between the coils, depending upon the operat­ ing mode of the system. The valve comprises a body (64) defining inlet and suction ports (22 & 28) for interconnection with the compressor and two reversing valve ports (36 & 40) for interconnection with the coils, a solenoid (196) operated pilot valve (153) and a slave valve (121) for selectively interconnecting the inlet port with one of the reversing valve ports, and a shuttle poppet valve (235) for interconnecting the suction port with the remaining reversing valve port.
